Secure now IC693PWR322 GE Fanuc DC Power Supply
The IC693PWR322 is a highly robust, wide-range DC-to-DC power supply module engineered specifically for the GE Fanuc Series 90-30 Programmable Logic Controller platform. Designed to operate in industrial facilities where standard AC power is either unavailable or undesirable, this module accepts a wide nominal input voltage of 24 VDC or 48 VDC (ranging functionally from 18 to 56 VDC). The IC693PWR322 converts this incoming voltage to provide highly stable outputs of +5 VDC, +12 VDC, and -12 VDC directly to the backplane, feeding the CPU and all installed I/O cards. Boasting a total output capacity of 30 watts, this power supply is designed with integrated switch-mode technology that ensures ultra-low voltage ripple and maximum protection against factory floor electrical surges, ensuring the uninterrupted processing of your logic controllers.

Expert Tips for Installation and Grounding
The IC693PWR322 must always be installed in the leftmost slot of any Series 90-30 baseplate (CPU, expansion, or remote). When wiring the DC input terminals, it is crucial to use adequately sized wire (typically 14 AWG) to prevent voltage drops over long runs. Strict attention must be paid to the grounding of the module. The ground terminal must be connected directly to the main cabinet’s earth ground bus using a low-impedance copper strap. Improper grounding is a leading cause of backplane communication faults and erratic logic behavior, as the power supply acts as the primary shield against electrostatic discharge (ESD) for the entire rack.
Maintenance and Memory Backup Advice
One of the most critical maintenance tasks associated with the IC693PWR322 involves its built-in battery backup circuit. This power supply houses a lithium battery that preserves the CPU’s volatile RAM memory (holding the logic program and register data) when the main DC power is removed. The front panel features a «BATT» LED that illuminates when the battery voltage drops below a safe threshold. It is an industry best practice to replace this battery every 12 to 24 months. Crucial warning: Always replace the battery while the main power to the IC693PWR322 is turned ON. Removing the battery while the system is unpowered will result in the immediate and irreversible loss of the PLC program.

Frequently Asked Questions (FAQs)
Q: Does the IC693PWR322 provide isolated 24 VDC output for field sensors?
A: No. Unlike some other Series 90-30 power supplies (such as the PWR321), the IC693PWR322 does not feature an isolated 24 VDC output terminal for external field devices. Sensors must be powered by a separate external supply.
Q: Can this power supply be used in an expansion baseplate?
A: Yes, the IC693PWR322 functions perfectly in both CPU baseplates and remote/expansion baseplates, provided it is installed in the dedicated leftmost power supply slot.
